Product description

The zBoost CONNECT ZB540 is a dual band 52dB system released by zBoost for single story urban dwellings up to 1,500 sq ft. Its patent-pending feedback technology allows there to be no vertical separation between the two antennas. This makes it the best solution for condos, lofts, and apartments.

The package includes everything you need to boost signal.

  • The signal antenna receives the signal, and mounts to a window in your apartment. The antenna mounts to the inside of the glass, meaning you don't have to go outside or up on your roof.
  • Ultra-thin RG59-mini cable then runs from the signal antenna to the base unit.
  • The base unit, indoor antenna and power supply are then placed in the center of the 1,500 sq ft where you want to improve signal.

Benefits of the zBoost CONNECT

  • Perfect for single story settings - no vertical separation needed
  • Increases your indoor signal - up to 1500 sq feet
  • Decreases dropped or missed calls
  • Easy to set up - comes complete with everything needed
  • No cradle or connections to your phone
  • Extends phone battery life (uses less power when signal is stronger)
  • Works with all phones and wireless data cards on 800 and 1900MHz (except Nextel, iDEN)
  • Works with all US carriers
  • Protects the carrier network using patent-pending technology
If you need to cover a larger area, then the zBoost ZB545 will cover up to 2,500 sq ft, and the ZB645 up to 5,000 sq ft.
